Varsity College registration Quick scheme

I am a student in my 5th year redoing x2 modules that I failed in my first year. I registered for only x1 module in the beginning of the year and I would only register for the 2nd module dependant that i pass the 1st semester module. According to vc I registered for both, when I clerley know I only registered for one as I needed to pay immediately upon registering. Is this a quick scheme to hold students at random for money? How do I register for a module and don't pay it as the website clerley asks for payment. Then I get told a contract was send to me but I didnt sign any contract??? But I am still held liable without my signature for acknowldgement??? Also my marks was not released to me in July when calling repeatedly. Know one even bothered to followup to explain to why my account was blcoked. But I was called to advise me that owe them money??? From year one its been a constant struggle its like a never ending roller coaster ride. Worst college ever would never recommend them. And now I owe them for money for a full module i wasnt even aware of? I think this college thinks people just have money laying around, why would anyone waste ones money like this???
